I know we have heard of it. AdSense!

Next, I have been trying to avoid this topic, but it calls for it.
ADSENSE!
Many people have different views on google adsense. Some say it is a 'scam', and others live off of it. When it comes down to it, adsense is only what you make of it.
When applying to become part of google adsense the process can be quite long through the eyes of most viewers. Filing out the information needed is not everyone's 'cup of tea'. After filling out the information, they will then say that you must wait for them to check your website, or blog, and see if it is what they are looking for. This process usually takes at least 2 days.
I must say, it is a 50/50 chance of being accepted. I, myself, have been turned down a couple of times until I have decided to give it one more try. Which I have, and I made it!.
[As you can see, there are ads all around my page].
If you have a blog or website, I highly recommend you sign up, you have nothing to lose, and it is completely free. You can only gain in this experience.

How does it work?

Well, to make a long complicated story short and to the point. Google puts ads on your website, and every time someone clicks on the ad, money goes to...guess...YOU!
Do NOT click your own ads. If you have been researching adsence for some time, i am more than positive you have heard this. They can and with no doubt about it WILL suspend your adsence account, which means no money for you :(

Traffic:
Simple.
The more people that come to your website, the more people see the ads.
The more people see the ads, the more people click the ads.
The more people click the ads, the more money in you pocket.

How do you get paid?
This is where we go back to the sign up section. You were previously asked to enter your address and such. Keep in mind that this is COMPLETELY safe. Once you reach 100 dollars in your adsence account, they send your check at the end of the month [as long as it is at or above $100]. They do not use paypal, although it would have been very convenient, it is easier for them to just send you a check. Reaching $100 dollars isn't that hard, as long as you know how to manage your account, keep people coming, maintain traffic, and get them clicking ads. All you have to do is keep an eye out, and make money while you sleep, provided everything goes according to plan.
